wxPython 4.2.1 wxGrid with GridCellChoiceEditor crash at destroy Grid/Frame
Operating system: Win10 Pro wxPython version & source: wxPython 4.2.1, pypi Python version & source: 3.8, python.org
Description of the problem:
I create a wxGrid with a GridCellChoiceEditor. If I open the GridCellChoiceEditor, at the destroy of the Frame/Grid I have the following error:
"any pushed event handlers must have been removed"
I have tried to work around the error using IncRef and DecRef, but this has not led to any success. With wxPython 4.1.1 I have no problems to run the code.
The same Error are by the following Example from wxPython.org:
